We observed a negative differential resistance (NDR) along with single-electron tunneling (SET) in the electron transport of electromigrated break junctions with metal-free tetraphenylporphyrin (H 2 BSTBPP) at a temperature of 11 K. The NDR strongly

We obtained organic Mott insulator nanowire by using the Nanoscale-electrocrystallization. The ac electrocrystallization provided nanowires only in the gap between two electrodes though dc yielded them over the anode surface. These nanowires ranged i

We measured the current–voltage (I–V) curves of 158 electromigrated break junctions with a Co(II) complex of tetraphenylporphyrin derivative (CoBSTBPP) at a temperature of 11 K within the applied bias ≤1.0 V. Symmetry I–V curves were observed

The fabrication of Au–molecule–Au junctions with an Al back gate electrode structure using an electromigration method was examined. Two kinds of molecules were used for the measurements of current–voltage ( I – V ) characteristics: 1,4-bis[(4

A simple approach to increase the reliability of nano-gap electrode fabrication techniques is presented. The method is based on maskless sputter etching of Au electrodes using a focused ion beam (FIB) and in-situ monitoring of the etching steps by me

We carried out a multiple simultaneous fabrication based on the nanoscale electrocrystallization to simultaneously construct molecular nanowires at two or more positions. This substrate-independent nanoscale electrocrystallization process enables nan

Maskless fabrication techniques of nanoelectrode with nanogaps are investigated, which use sputter etching technique by Ga focused ion beam (FIB). The etching steps are reliably controlled in situ by monitoring a current fed to the films. 30keV Ga FI

The optical controllability of single-electron tunnelling using an organic molecular Coulomb island consisting of a porphyrin derivative was examined. A double-barrier tunnelling junction (DBTJ) consisting of a Si/SiO2/molecule/SiO2/Au multilayer exh

Nano-crystal growth based on an electrochemical method was carried out to construct self-assembling molecular nanowires. For nanoscale electrocrystallization, an axially-substituted phthalocyanine solution and substrates with two electrodes formed by
